Relationships between Tree Diameter, Height, and Stocking in Even-Aged Eucalypt Stands in Pointe-Noire (Republic of Congo)

The study highlights the complex dynamics governing the growth of forest stands, particularly in eucalyptus plantations in Congo. Factors such as soil fertility, planting density, clone genetics, and resource competition significantly influence forest productivity. Thinning practices, when well implemented, help to rebalance competition among trees and maximize diameter growth. However, forest growth models, like Vanclay’s model, must be adapted to local conditions to provide more accurate and relevant predictions. Despite the progress made, questions remain about the best way to optimize forest stand management. The use of more sophisticated models that can account for the diversity of ecological conditions and management practices represents a major challenge for researchers and forest managers.
